The Rifle Shooter by David Tubb is an excellent read to drive home the fundamentals of precision shooting (see section 1 Mechanics).
I first met David Tubb at the SHOT Show last year and he was talking about a new scope reticle that he had designed (David, if you're reading this drop me a line so KU can check it out!). He was also kind enough to send me a copy of his book which I just finally got around to reading.
While I'm not a big fan of match shooting (what was that Hemingway quote?....), I do see the benefits and I would recommend picking up David's book. I especially like his section on mental preparation and this can be applied to multiple disciplines including all the Airsoft bubbas.
If you guys pick up a copy be sure to drop me a line via the Fireteam page and let me know what you think.
